I have had a look at all the questions you have asked on this site and it is clear to me that you have not yet read/understood the question guidelines. At least 7 of your 9 question have violated the 1st guideline.

A few simple rules when posting your question.
1) Have you searched or Googled for a solution?
2) Be specific! Don't ask "I need to write a booking application". Specify exactly what it is you need help with.
3) Keep the subject brief but descriptive. eg "How do I change the dialog colour?"
4) Keep the question as concise as possible. If you have to include code, include the smallest snippet of code you can - do not dump your entire codebase.
5) Tag your question appropriately.
6) Your question may be edited or retagged by others. Anything inappropriate will be removed.
7) If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
8) Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
9) Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read.
10) Do not be abusive, offensive, inappropriate,harass anyone on the boards or post ads or spam. Doing so will get you kicked off and banned. Play nice.
